Item organization / main palette categories #2168
Description
Description of the feature
A way to group up similar items into categories as the current main palette becomes messy with the more UCPs installed with some directly intersecting the main bee groups (not automatic, user driven).
This is also helpful if you have many items that work together that are stranded amongst the sea of items
For example these fizzler type items would be very useful to have a single category to themselves:
Why should this be implemented
This would make the UI much nicer to use if someone were to add ucps/more items that are added into beemod itself.
Additional information
This would be a rough example on what it would look like
